/diy/ - Do It Yourself

>>2441989
just finished repairing the board. rigged it up with a thermostat and a light for the reversing valve solenoid. set it to 30 minutes turned on the heat. then shorted the defrost thermostat connection and it engaged the solenoid while disengaging the fan. I didn't even need the 2 IC's I ordered.

So I fixed it with:
6 capacitors $1.63.
1 transistor .64
1 relay $4.92
1 diode .06
shipping was $11 because I had to go to multiple places.
so I fixed a $150 board for $18.25.
all parts except the transistor came from digikey.

I pre-emptively ordered parts from my AC units. I have spare capacitors and the board.

I bet you I could rebuild the fan motors, I did that for my brothers cooler motor. cost me about $12 for new bearings from mcmaster carr.
